Difference between Hypoglycaemia and Hyperglycaemia

Hypoglycaemia and hyperglycaemia are two different types of diabetes. Many people do not understand the difference between the two and often use the terms interchangeably. This can be dangerous as it can lead to confusion about how to treat each condition. In this blog post, we will look at the differences between hypoglycaemia and hyperglycaemia and explain how they should be treated.

What is Hypoglycaemia?

  • Hypoglycaemia is a condition characterized by low blood sugar levels. Hypoglycaemia can occur in people with diabetes when they take too much insulin or other blood sugar-lowering medications.
  • It can also occur in people who don’t have diabetes after eating a meal high in sugar or carbohydrates. Hypoglycaemia can cause a variety of symptoms, including headaches, fatigue, sweating, and heart palpitations.
  • If left untreated, it can lead to coma and death. Hypoglycaemia can be treated by eating or drinking something high in sugar, such as fruit juice or candy. In severe cases, injection of glucagon or intravenous glucose may be necessary.

What is Hyperglycaemia?

Hyperglycaemia is a condition where there are high levels of sugar in the blood. It can be caused by a number of factors, including eating too much sugar, not getting enough exercise, or having an underlying medical condition. Hyperglycaemia can cause a number of symptoms, including headaches, tiredness, and blurred vision. If left untreated, it can lead to serious complications, such as diabetes. Hyperglycaemia can be treated with dietary changes, exercise, and medication. In severe cases, hospitalization may be necessary.

Difference between Hypoglycaemia and Hyperglycaemia

Hypoglycemia, also known as low blood sugar, occurs when there is not enough sugar in the blood to provide energy for the body’s cells. Hypoglycemia can be caused by several factors, including skipping meals, consuming too much alcohol, or strenuous exercise. Symptoms of hypoglycemia include confusion, dizziness, sweating, and heart palpitations. If left untreated, hypoglycemia can lead to coma or even death.

Hyperglycemia, on the other hand, occurs when there is too much sugar in the blood. Unlike hypoglycemia, hyperglycemia is usually caused by diabetes mellitus. Symptoms of hyperglycemia include increased thirst, increased urination, and blurred vision. If left untreated, hyperglycemia can lead to diabetic ketoacidosis, a serious condition that can be fatal.

Hypoglycemia and hyperglyceamia are both serious conditions that require immediate medical attention. However, it is important to remember that they are two completely different conditions with different causes and different symptoms.


Hypoglycaemia is a condition characterised by low blood sugar levels, whereas hyperglycemia is characterised by high blood sugar levels. Both conditions can be dangerous if left untreated, so it’s important to know how to recognise the symptoms of each and seek medical help if necessary.
